SKATE AND CASTER ROLLER.

SPECIFICATION forming part of Letters Patent No. 343,185, dated June 8, 1886.

Application filed September 8, 1885. Serial No. 176,512.

To all whom, it may concern.-

Be it known that I, STEPHEN O. MENDEN- HALL, a citizen of the United States, residing at Richmond, Wayne county, Indiana, (present business address Cincinnati, Ohio,) have invented a new and useful Improvement in Skate and Caster Rollers, of which the following is a specification.

My present invention relates to an improved method of applying a series of antifriction rollers around the axle orjournal of a skate or caster-roller; and it consistsin chambering the floor-roller on each side, placing a plain circular ring or cylinder within each of the chambers, and a plate or washer against the inner wall of the chambers within the rings or cylinders to prevent the rollers coming in contact with the wood or other material, arranging a series of loose anti-friction rollers within such ring, and retaining the whole in position by a circular plate of greater diameter than said ring, and fixed to the body of the floorwheel or roller without and around the same. I

In order that the invention may be better understood, I will proceed to describe it with reference to the accompanying drawings, in

which-- Figure I represents in vertical section a floor wheel or roller of wood or other suitable material, chambered out to receive anti-friction bushings. Fig. II is a side elevation of the same, the bushing being in position, but the cap-plate being removed. Fig. III is an axialsection of the roller with the bushing and cap-plate in position. Fig. 1V is a similar View showing a modified form of fastening for the cap-plate.

1 may represent a floor wheel or roller of wood, hemacite, or other hard material, having circular chambers 2 at each side, and axleopening 3 for the journal or axle of the skate or caster.

4 4 are rings or cylinders, preferably of steel, placed in the chambers of the roller and affording ways for the loose anti-friction rollers 5, arranged in annular series around the axle 6.

7 is a washer having a central aperture of greater diameter than the axle, and placed against the inner walls of the chambers 2, to

(ModeL) prevent the friction of the rollers 5 on the wood or other material of the floor wheel or roller.

8 8 are cap-plates of greater diameter than the rings 4, and having in the preferred form of the invention (shown in Fig. III) a rim or circular series of sharp points, 9, driven into the body of the roller or into a groove, 10, Fig. II, therein, in order to retain it in' place.

In Fig. IV, I have shown screws 11, employed for fixing the cap-plate to the roller.

It is apparent that the improved roller is equally applicable to skates and casters, in the former case being preferably made with a cylindrical and in the latter case with a rounded bearing-surface.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. The combination, with a floor-wheel recessed or chambered at each side, of the bearings herein shown and described, each bearing consisting of a series of loose anti-friction rollers,

a plate or washer interposed between the rollers and the inner wall of the chamber, a ring or cylinder surrounding the plate or washer and the rollers, and separablefrom the former while forming a track for the latter, and a cap to the chamber of greater diameter than the ring or cylinder and fixed to the wheel without and around the same, substantially as set forth.

2. The combination of a floor-wheel chambered at each side and having annular grooves
